Mitsubishi MSZ-GE12NA Expansion Valve
Expansion valves are used in AC systems and permits the refrigerant to spread back into gas state from a liquid. The AC in a split system would not yield any cooled air if it were to lack a properly working expansion valve.

- The air conditioned air is definitely not as cold as you are accustomed to coming from the air handler
